The business, based in Lincolnshire, has been at the forefront of asparagus variety testing since it planted what was thought to be the world's largest test in 2004.
This year's trial contains more than 25 cultivars from eight breeders, including Nunhems and the University of Guelph in Canada.
The asparagus trials are managed by Marie-Laure Bayard, who has been overseeing this part of the business since 2006.
She said: "It will be very interesting to see how our results compare with those across the globe. It is our ultimate aim to find improved asparagus cultivars."
